Henry I hear ya.
I have 3-4 F's, 1-F2 an FM2n and a Nikkormat FTN and an FT2 and I was amazed at how smooth the film advance was on the mats.
Both meters work in them and I gotta say they hold a candle to any of the more "pro" models.

The mats actually have beter MLU than my F's but I still grab the F's first. IDK just something about the way thy are balanced/handle.
